The Boston Scientific ENDOTAK RELIANCE DF1 Defibrillation Lead (REF 174) is a transvenous endocardial lead designed for chronic implantation in the right ventricle as part of an implantable cardioverter defibrillator (ICD) system. The ENDOTAK RELIANCE family is engineered to deliver high-voltage defibrillation therapy together with bradycardia pacing and intracardiac sensing, and is offered in a DF1/IS-1 trifurcated connector configuration for compatibility with legacy DF1-compatible pulse generators.
Key Features
- Transvenous endocardial defibrillation lead with integrated pace/sense and shock electrodes
- DF1/IS-1 connector configuration for compatibility with DF1-compatible ICD and CRT-D pulse generators
- Designed for right ventricular placement with steroid-eluting tip intended to reduce acute and chronic pacing thresholds
- Silicone and polyurethane insulation construction typical of the ENDOTAK RELIANCE platform
- Available in single-coil or dual-coil configurations depending on model variant
- Specific fixation mechanism (active or passive) for REF 174: Not specified in the located sources
Clinical Applications
- Intended for use as the ventricular defibrillation lead component of an ICD or CRT-D system
- Supports delivery of high-voltage defibrillation and cardioversion therapy for ventricular tachyarrhythmias
- Provides intracardiac electrogram sensing and bradycardia pacing in conjunction with a compatible pulse generator
- Suitable patient indications and contraindications: refer to the manufacturer Instructions for Use (IFU)
